BOW CHAIN: CO₂ emissions 2018–2025

BOW CHAIN against its type

Built in 2002, it is 8 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 23,190 gross tonnage it is smaller than 51% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 25 other vessels here, 20 of them chemical tankers. The reported port of registry changed: Bergen (2018–2024), then Majuro (2025).

Its 3,788 t of CO₂ for 2025 is 32% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 271.7 kg CO₂, close to the type median of 250.2 kg. It logged 1,114 hours at sea against a median of 2,109 hours for its type that year. 3.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2019 (9,479 t) and the lowest 2024 (1,328 t). Its efficiency percentile within the type went from 17 in 2018 to 60 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 816 of 1,348 qualifying chemical tankers by EEOI, at the 60th percentile. The dashed line is the type median, 14.4; this vessel reported 17.3.

EEOI divides emissions by transport work, which for this vessel and year was 219,352,056 tonne-miles over 13,942 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 11.1% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 185.3% while distance sailed rose 305.9%and CO₂ per nautical mile fell 29.7%.That points mainly to how much the vessel sailed, rather than the other.
